CVE-2026-113105 [HIGH] CWE-825 chromium-browser: chromium-browser: arbitrary code execution inside sandbox via crafted HTML page
chromium-browser: chromium-browser: arbitrary code execution inside sandbox via crafted HTML page
A flaw was found in chromium-browser. A remote attacker can exploit a use-after-free vulnerability—where memory is improperly accessed after being deallocated—in the Extensions component to achieve arbitrary code execution inside the browser sandbox. By convincing a user to visit a specially crafted HTML page, the attacker triggers memory corruption to run unauthorized code within the restricted sandbox environment.
